BackgroundWe evaluated the effectiveness and safety of a zotarolimus-eluting ZES versus a sirolimus-eluting SES coronary stent in a large cohort of patients treated with one of these stents in Western Denmark.

MethodsA total of 6,122 patients treated with ZES n=2,282 or SES n=3,840 were followed for up to 27 months. We ascertained clinical outcomes based on national medical databases.

ResultsIncidence of target lesion revascularization no. per 100 person-years was 5.3 in the ZES group compared to 1.9 in the SES group adjusted hazard ratio HR=2.19, 95% confidence intervals CI: 1.39-3.47; p=0.001. All-cause mortality was also higher in the ZES group ZES: 6.3; SES: 3.3; adjusted HR=1.34, 95% CI: 1.05-1.72; p=0.02, while stent thrombosis ZES: 1.2; SES: 0.5; adjusted HR=1.98, 95% CI: 0.75-5.23; p=0.14 did not differ significantly.

ConclusionsIn agreement with previously published randomised data, this observational study indicated that the ZES was associated with an increased risk of death and TLR in a large cohort of consecutive patients.
